Big project is to get through the Gospels in Koine. Still only halfway through Matthew.
I don't know if you've heard of it but the Nestle-Alard Interlinear will help you greatly. I used it in my old seminary days and found it very useful. However, I had two years of classical Greek in my prior university days which makes koine relatively simple. How far have you progressed? What was very interesting also is how many Greek transliterations result in perfect Latin words!
